200 nickel is over 98% pure, so it offers outstanding corrosion resistance along with good formability, weldability, and electrical conductivity. It is often used in food-processing equipment and chemical shipping drums.

Often used for cryogenic tanks and fasteners, 718 nickel will maintain its high strength in temperatures from -300° to 1200° F, even after long-term exposure. It can be further strengthened by heat treating. This material is comparable to Inconel 718.

Because Invar 36 holds its size and shape when temperatures rise, this nickel-iron alloy is the go-to material when dimensional stability is required. It is commonly used when precision is a priority, such as for scientific instruments and optical devices.

Even in temperatures up to 2000° F, Alloy X nickel offers good strength and weldability, along with excellent oxidation resistance. It's often used for components in gas turbine engines and furnaces. This material is equivalent to Inconel HX and Hastelloy X.
